Fatigue Cracking in Asphalt

Fatigue Cracking in Asphalt Fatigue cracking is that cracking and chipping we see on our roads almost anywhere we go It seems to be quite harmless but a smart road manager knows this is a sign that the pavement is on its way to failure.

Designing mixes for top performance

This type of distress is called top-down cracking Classic, bottom-up, fatigue cracking is usually found in thinner pavements constructed on a granular base (or other base layer) The top-down cracking is most often observed in thicker pavements, or asphalt pavements constructed over a rigid base (like an asphalt overlay of a concrete pavement).
